S2719DGF, Sapphire R9 285, no 144Hz, thread #1

Hi ,

Just bought the monitor this Black Friday. Looks great but I can't get it to run at 144Hz. Have tried everything that came to mind: 

- used the included HDMI cable
- mDP to DP (mDP to DP along a DP-DP cable)
- mDP to hdmi (included cable with an adapter)
- installed latest drivers

My video card is a Sapphire R9 285 ITX and it has an HDMI and two mDP ports. I'm currently running at 1440p and the only refresh rates windows 10 64 shows is 60Hz. Have also tried 1080p, same result.

 

Any help would be much appreciated.

Problem solved. 

I bought a DP 1.2 cable and it worked.

Here is the User's Guide.

We know that both the S2719DGF and S2419HGF are hardware capable of AMD FreeSync. This has to be an AMD setting issue somewhere.


The monitor Menu- Game used these settings;
Overclock = On
FreeSync = On
Exit the Menu

What happens when you then press the #2 FreeSync button on the monitor?

Did you test using this specific setup?
Sapphire R9 285 ITX mDP out port --> mDP to DP cable --> S2719DGF DP in port

currently running on the hdmi cable that came with the monitor. 

#2 button shows freesync is on. 

Can't turn on the overclock funciton . Currently it's off .

Don't have another pc to test the monitor on. Any new suggestions ?

My mistake, Overclock only refers to using DP to set 155Hz. So you not being able to set it is correct. You have verified via the picture above that the HDMI cable is plugged into HDMI 2 2560x1440/144Hz and not HDMI 1 2560x1440/60Hz?

 

To see Overclock On, test this =
Sapphire R9 285 ITX mDP out port --> mDP to DP cable --> S2719DGF DP in port

Hi again, 

The HDMI cable is indeed plugged into the #2 HDMI monitor input. I'm so disappointed. Not blaming the monitor but I really bought this mainly for it's 144Hz refresh rate.

The fault lies with the 2014 Sapphire R9 285 which only supports only support DP 1.2 and HDMI 1.4. You need to get a new AMD video card that has DP 1.4. (AMD RX 460/470/480/560/570/580/Vega)

Nice :) Thanks Chris! I really wasn't expecting the video card to be the culprit. At least now I know what I want for Christmas :)

One more thing though, wouldn't hdmi 1.4 be able to support a higher refrash rate at a lower res? I get max 60hz at both 1080p and 720p on both hdmi and dp.

Edit2: just realized that the dp cable I was using was 1.1  Will buy another 1.2 one and try again.

I found several threads on other forums where people mentioned that DP 1.2 can handle 1440p up to 165hz and 4k up to 75hz.

When you switched to using dp1.2 cable you were able to get more than 60hz? I am having the same issue with my r9 fury and am wondering if I should update my cable.

there appears to be some kind of signal handshake issue with R9 cards to this monitor (could be driver based or port based on monitor). I finally managed to get my R9 Fury to work with the S2719DGF at 144hz. I had swapped it out with an RX460 to test signal, restart pc couple of times due to windows prompts and hardware changes. Re-inserted Fury, and Windows recognized it's 144hz capable.

I had the same problem with R9 390 and I bought a certified VESA 1.4 cable and it worked!

Grdreamer,

So you tested the supplied S2719DGF HDMI to HDMI cable on the center HDMI 2.0 port and it did not work to get 144Hz? Can you post the link to that specific working retail certified VESA 1.4 cable?
